PHONOGRAPH.

SPECIFICATION forming part of Letters :Patent No. 698,082, dated April 2e, 1902.

Y i Application filed October 21, 1901. Serial No. 79,425. (No model.)

.To all whom it may concern:

Be it known that I, OHARLEs WILLIAM VER- NON, `inventor, of the city of Toronto, in the county of York, in the Province of Ontario,

Canada, have invented certain new and useful Improvements in Phonographs, of which the following is a specification.

My invention relates to improvements in phonographs and the obj ect of the invention Io is to improve the details of construction and produce a more simple and eflicient device. To this end the invention consists in the construction and arrangement hereinafter described, and particularly pointed out in the To carry out these objects, I have constructed and arranged my phonograph in the manner which I shall now describe.

Figure l is a perspective View of a phonograph-frame constructed in accordance with zo myinvention. Fig. 2 is a perspective detail, partiallyin section, of the speaker or recorder arm. Fig. 3 is a longitudinal section through the cylinder and tapered end of the arbor upon which the cylinder iits. Fig. 4 is a de- 2 5 tail of the feed-nut. Fig. 5 is a detail showing the manner of hinging the gate.

In the drawings like letters of reference indicate corresponding parts ineach figure.

A is the bed-plate or base of the machine,

3o which has the'outwardly-extending portions A', A2, A3, A4, and A5.

ct', a2, a3, a4, and a5 are pillars, which are formed separately, being turned into any suitable design. The pillars are secured.l to the 3 5 ends of the projections by machine-screws extending outwardly through the arms of the projections into the pillars. It is of course not necessary to describe the exact form of screw, except that I may sayitY has a flush 4o head at the bottom. When the pillars are being properly alined, so as to carry the frame, pin-holes are made through the base into the pillars, one at each side of thescrew, and pins put into them, so as to setit rigidly.

Bis a bar extending from the pillar a to the pillar a5 and secured to the top of the pillars by the countersunk screws.

C is the main shaft or arbor ofthe phonograph, which is supported at one end in suit- 5o able journals at the top of the pillars a3 and d, the pillar a being formed and attached to the bed-plate similarly to the other pillars referred to. The opposite end of the arbor C is tapered and has its bearing on the conical end of the pin c, which extends through the gate C. The gate C' is hinged at one end between the jaws C?, being held therein by the pin C8. (See detail Fig. 5.) The gate C', it will be y noticed in reference to Fig. 1, has a spring i clasp c3, having a hole c4, through which ex- 6o tends the pin c5, projecting from the pillar a.

D is a cylinder on which the record is placed. The'cylinder'D may be a large cylinder, as indicated in Fig. 8, or a small cylinder, as indicated in dotted lines in Fig. 3 65 and full lines in Fig. I. In order to place a large or small cylinder in position on the tapered end of the shaft C, the gate O has to be swung out, when the cylinder may readily be withdrawn from the tapered end 'of the7o shaft C and a larger or smaller one placed thereon. On account of the end of the shaft being tapered it will be understood that a cylinder may be taken off and a new one substituted with ease. 75

E is the driving-pulley, which is suitably secured on the arbor or shaft C near one end.

F is the recorder or speaker arm, which is curved in form, as shown, and provided in the center .with an orifice f,- in which the 8o speaker or recorder or stylus is placed. The free end F' of the arm F is concentric to the Vrod G, which is suitably held at the ends in j the pillars a2 and a4. The opposite end of the l arm F is provided with a circular opening f and projecting lugsfz, through which extends the clamp-screw f3.

I-I is a sleeve which extends through the openingf'.

I is a spring secured underneath the arm` Fby screws il and having located on its free, end the pin i', which is designed to engage oneor other of the recesses h and h,this depending on the height it is desired to raise the arm, and consequently the recorder or speaker. If the large cylinder is used, the pin fi isinserted into the recess h, so as Ato bringthe recorder or speaker close to thecylinder; but if the small cylinder is used the spring I is thrown out and the pin Il roo transferred to the lowermost notch 7L', thus adjusting the arm Without adjusting the sleeve, and thus serving to keep the springarm J and the nut K pivotally held in the end jaw j of the arm in contact with the screw feed-thread of the shaft or arbor C, no matter whether the large cylinder is used or the small one. It will be noticed that the nut K is pivotally held at the center upon the pin 7c and acted upon at the ends by the spiral springs la', extending underneath the arm J into recesses in the nut. The nut K is provided with a bottom arc-shaped recess k2, which is threaded to correspond with the thread on the arbor C. The object of pivoting the nut is to provide more or less rock to it, so that the arm J, which is set with the constant pressure on the nut, will allow of the nut accommodating itself To any slight adjustment of the arm F.

The arm F is adjusted by means of a setscrew L, which extends through a bracket L', fastened to the end F of the arm F by another set-screw L2.

L3 is a handle pivoted at the upper end in the jaws Z of the bracket L and provided intermediate of its length with an arc-shaped recess Z. By pushing upwardly upon the arm LS the arm F may be raised so that it may be locked from vertical displacement and slid backwardly and forwardly with the recorder or speaker raised clear of t-he record. By raising the handle L3 sufficiently the notchl may be brought over the bar B, whereupon the arm may be swung backwardly and forwardly clear of the record on the cylinder.

It will of course be understood that when the shaft or arbor is driven by means of the pulley E the nut K, engaging with the thread on the arbor C,will, on account of the arrn J being secured to the sleeve H, as indicated, move the arm F longitudinally, so that the recorder or speaker is in operative contact with the record on the cylinder.

By the construction I have above described it will be seen that I am enabled to produce the frame of the machine very cheaply and avoid the difficult-y of centering the arbors and supporting-rods, as the pillars may be formed up very accurately and the portions and arbor supported by the pillars maybe readily and accurately itted to them. It will also be seen that I may adjust the recorderarm for diierent-sized cylinders without interferin g with the feedingnut,which engages with the screw-thread on the shaft or arbor. I am also enabled to provide for themovement of the recorder-arm over the cylinder Without any danger of it coming in contact with the record, so that such arm may be readily placed in any position on the record so as to repeat any portion thereof as may be desired.

From the construction of the arbor with the end tapered andthe cylinder having a tapered hole and being hollow, as indicated, it will be seen that such cylinder may be readily removedand another one substituted. It will also be understood on account of the fine adjustment of the feeding-arm the record may be saved and used until worn out.

Nhat I claim as my invention is- I. The combination with the frame, the arbor suitably journaled therein, the side rod forming one side of the frame, the sleeve longitudinally adjustable thereon, the recorderarm secured at one end to the sleeve an d suit` ably supported at the opposite end on the frame, the feed-arm suitably secured to the sleeve and provided with a nut having an arc-shaped recess threaded so as to engage with the screw-threaded end of the arbor and said nut being centrally pivoted in the end of the arm and spring-held as and for the purpose specified.

2. The combination with the arbor threaded at one end and suitably journaled in the frame, the cylinder suitably secured to the arbor, the longitudinal side rod, the sleeve fitting thereon and provided with radiallydisposed notches, the recorder-arm secured to the sleeve, the feed-arm secured to the sleeve at one end,l the nut secured to the 0pposite end of the feed-arm and meshing with the threaded end of the arbor, the spring on the recorder-arm provided with an end pin designed to engage one or other of the two notches in the sleeve as and for the purpose specied.

The combination with the arbor, suitably journaled, and the cylinder fitting thereon, ot' the recorder-arm pivotally held at one end and provided with an arc-shaped end, concentric to the pivoted rod, the side bar of the frame, the bracket secured on the concentric end and the setscrew extending through the bracket and resting on the side bar of the frame as and for the purpose specified.

4.. The combination of the arbor, suitably journaled and the cylinder fitting thereon, of the recorder-arm pivotally held at one end and provided with an arc-shaped end concentric to the pivotal rod, the side bar of the frame, the bracket secured on the concentric end and the set-screw extending through the bracket and resting on the side bar of the frame and the handle pivoted on the end of the bracket and provided with a notch designed to engage with the bar and locking the arm, so as to slide iu the raised position as and for the purpose specified.
